WHEEL-RETAINING SPINDLE-CAP.

Specification of Letters Patent.

Patented Sept. 28, 1920.

Application filed April 12, 1920. Serial No. 373,116.

T 0 all whom it may concern.

Be it known that I, CHARLES A. LINDBERG, a citizen of the United States,residing at Sturgis, county of St. Joseph, State of Michigan, haveinvented certain new and useful Improvements in IVlieel-RetainingSpindle-Caps, of which the following is a specification.

This invention relates to improvements in wheel retaining spindle caps.

The main object of this invention is to provide an improved wheelretaining spindle cap which is very secure when engaged and at the sametime may be quickly released and is neat and attractive in appearance.

Further objects, and objects relating to structural details willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing forming a part of thisspecification, in which:

Figure I is a side elevation of a structure embodying the features of myinvention.

Fig. II is a detail view with the axle and wheel partially broken away,parts of the cap and spindle being shown in vertical central section ona line corresponding to line 2-2 of Fig. I.

Fig. III is an inside view of the disk-like spindle collar member priorto the bending of the locking dog supporting arm.

In the drawing similar reference characters refer to similar partsthroughout the several views.

' Referring to the drawing, 1 represents the axle and 2 the wheel of achilds carriage for which my improvements are particularly designed andadapted by me in practice. The axle is provided with a thrust collar 8at the inner end of the spindle 4. I provide a cup-shaped cap 5 formedas a sheet metal stamping, the rim of the.cap being prefr erablyoutwardly flared at 6 to provide a bearing for the outer end of the hub.

At the inner end of the cap I secure a disk-like spindle collar member 7having the flange-like collar 8 formed integrally therewith. The spindle4 is provided with a hole 9 while the collar 8 has a hole 10 adapted tobe brought into register with the hole in the spindle. Opposite theseholes the collar member 7 is provided with an inwardly projecting arm 11having a hole 12 therein'through which the dog 18 is slidably arranged.The dog has a return bend at its inner end providing an engaging portion1 1 which passes through the openings in the collar and spindle whenthey are brought into alinement as shown in Fig. II, locking the cap tothe spindle.

The collar member and the arm 11 are formed integrally as a sheet metalstamping. The dog 13 is provided with a cap 15 slidable in the hole 16inside the cap, the coiled spring 17 being arranged between the head 15and the arm to urge this dogor detent to its engaging position.

By this arrangement of parts, I provide a structure which is simple andeconomical to produce, convenient to manipulate, and neat and attractivein appearance, same being well adapted for use in childrens carriagesand vehicles for which it is, as stated, especially designed.

I have not attempted to illustrate or describe certain adaptations of myimprovements which I contemplate and which might be desirable for othertypes of wheels as I believe the disclosure made will enable thoseskilled in the art to which my invention relates to embody or adapt thesame as may be desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. The combination with a spindle and wheel, of a spindle cap having aside opening therein, a disk-like member secured in the inner end ofsaid cap and provided with an inwardly projecting flange-like spindlecollar and an inwardly projecting arm having an opening therein alinedwith said opening in said cap, said collar and spindle havingregistering holes opposite said arm, a locking dog slidable in said holein said arm and having a cap-like head slidable in said opening in saidcap, the inner end of said dog having a return bend therein engagingsaid holes in said collar and spindle, and a coiled spring arranged onsaid dog between the said head and supporting arm.

2. The combination with a spindle and wheel, of a spindle cap having aside openwheel, of a spindle cap,-a collar member provided with aspindle collar and an arm, said collar and spindle having holes adaptedto be brought into register, a locking dog slidable in said arm and cap,the inner end of said dog having a return bend therein engaging saidholes in said collar and spindle, and a spring urging said dog to itsengaging position.

4:. The combination with a spindle and wheel, of a spindle cap, a collarmember provided'with a spindle collar and an arm,

said collar and spindle having holes adapted to be brought intoregister, a locking dog slidable in said arm and cap to engage saidholes in said collar and spindle, and a spring urging said dog to itsengaging position;

In witness whereof I have hereunto set my hand and seal in the presenceof two witnesses.
